I’m using a function that ties into fields on one of my other registration forms that is not part of Pie Register. I’m using

xprofile_get_field_data('Gender', $user_id);

What I’d like to know is what is the equivalent to this in Pie Register if I have a radio field with a label of Gender2 and a value of male-free? I’d like to be able to target that just like I am able to target the xprofile field in my code above.
